Loading all the images from gallery into the Appli

Question

I am creating an application wherein I need all the images in the gallery into my application that has a girdview in it. I want all the images from all the folders to appear in the gridview.

String[] proj = { MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID };
actualimagecursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, proj,
                      null, null, MediaStore.Images.Media.DEFAULT_SORT_ORDER);

actual_image_column_index = actualimagecursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID);
actualimagecursor.moveToPosition(position);
String i = actualimagecursor.getString(actual_image_column_index);

I have added this code into my code but i get only the sd card images no other folder images are obtained. How can i get all the images from the gallery?

Thanks in advance.

intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURE);

        Log.e("fatch in","images");

Answer 4

You can not get results with just one query, try to instantiate two different Cursors. Since you have already added EXTERNAL_CONTENT_URI, here is another:

 actualimagecursor2 = managedQuery(MediaStore.Images.Media.INTERNAL_CONTENT_URI, proj,
                      null, null, MediaStore.Images.Media.DEFAULT_SORT_ORDER);

Answer 6

You are using MediaStore.Images.Media.EXTERNAL_CONTENT_URI which is only the external storage.For the internal there is MediaStore.Images.Media.INTERNAL_CONTENT_URI. You can use a MergeCursor to combine both query results.
